# What Tecnoglass Inc.'s (NASDAQ:TGLS) ROE Can Tell Us

One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. We'll use ROE to examine Tecnoglass Inc. (NASDAQ:TGLS), by way of a worked example.

Over the last twelve months Tecnoglass has recorded a ROE of 9.2%. Another way to think of that is that for every \$1 worth of equity in the company, it was able to earn \$0.092.

### How Do You Calculate ROE?

The formula for ROE is:

Return on Equity = Net Profit Ã· Shareholders' Equity

Or for Tecnoglass:

9.2% = US\$17m Ã· US\$182m (Based on the trailing twelve months to June 2019.)

Most readers would understand what net profit is, but itâ€™s worth explaining the concept of shareholdersâ€™ equity. It is the capital paid in by shareholders, plus any retained earnings. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.

### What Does Return On Equity Mean?

Return on Equity measures a company's profitability against the profit it has kept for the business (plus any capital injections). The 'return' is the profit over the last twelve months. A higher profit will lead to a higher ROE. So, all else being equal, a high ROE is better than a low one. Clearly, then, one can use ROE to compare different companies.

### Does Tecnoglass Have A Good Return On Equity?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. If you look at the image below, you can see Tecnoglass has a similar ROE to the average in the Basic Materials industry classification (9.2%).

That isn't amazing, but it is respectable. ROE tells us about the quality of the business, but it does not give us much of an idea if the share price is cheap.

### How Does Debt Impact ROE?

Most companies need money -- from somewhere -- to grow their profits. That cash can come from retained earnings, issuing new shares (equity), or debt. In the first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

### Combining Tecnoglass's Debt And Its 9.2% Return On Equity

It's worth noting the significant use of debt by Tecnoglass, leading to its debt to equity ratio of 1.44. Its ROE isn't too bad, but it would probably be very disappointing if the company had to stop using debt. Investors should think carefully about how a company might perform if it was unable to borrow so easily, because credit markets do change over time.

### The Key Takeaway

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. Companies that can achieve high returns on equity without too much debt are generally of good quality. If two companies have around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.

Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too.
